  • Method for coating micromechanical parts with high tribological performances for application in mechanical systems
    Patent number: 8770827
    Abstract: Method for coating micromechanical components of a micromechanical system, in particular a watch movement, comprising: providing a substrate component to be coated; providing said component with a diamond coating; wherein diamond coating is provide by CVD in a reaction chamber and during CVD deposition, during the last portion of the growth process, a controlled change of the carbon content within the reaction chamber is provided, thereby providing a change of the sp2/sp3 carbon bonds in the vicinity of the surface. Corresponding micromechanical components are also provided.
    Type: Grant
    Filed: May 18, 2010
    Date of Patent: July 8, 2014
    Assignee: The Swatch Group Research and Development Ltd
    Inventors: Detlef Steinmuller, Doris Steinmuller, Herwig Drexel, Slimane Ghodbane, David Richard, Pierre Cusin
  • METHOD FOR COATING MICROMECHANICAL COMPONENTS OF A MICROMECHANICAL SYSTEM, IN PARTICULAR A WATCH AND RELATED MICROMECHANICAL COATED COMPONENT
    Publication number: 20120141800
    Abstract: Method for coating micromechanical components of a micromechanical system, in particular a watch movement, comprising: providing a substrate component to be coated; providing said component with a diamond coating; wherein said diamond coating conductivity is increased in order to reduce dust attraction by the coated component when used in said micromechanical system. Corresponding micromechanical components and systems are also provided.
